WWII US Airborne Australian Made Officers Bush Cap. This is a very unusual Officer's Slouch Hat is roughly size 7 1/4 having a set of Pin Back US Army Airborne Jump Wings pin through the felt body along with a Luxenberg marked Officers Insignia applied to the front with a silver Officer's Hat Cord. The cap is makermarked but is difficult to read. Most likely a member of the 11th Airborne who wore this hat. Excellent. The 11th Airborne Division ("Angels") was a United States Army airborne formation, first activated on 25 February 1943, during World War II. Consisting of one parachute and two glider infantry regiments, with supporting troops, the division underwent rigorous training throughout 1943. It played a vital role in the successful Knollwood Maneuver, which was organized to determine the viability of large-scale American airborne formations after their utility had been called into question following a disappointing performance during the Allied invasion of Sicily. Held in reserve in the United States for the first half of 1944, in June the division was transferred to the Pacific Theater of Operations. Upon arrival it entered a period of intense training and acclimatization, and by November was judged combat-ready. The 11th Airborne saw its first action on the island of Leyte in the Philippines, but in a traditional infantry role. In January 1945 the division took part in the invasion of Luzon. The two glider infantry regiments again operated as conventional infantry, securing a beachhead before fighting their way inland. The parachute infantry regiment was held in reserve for several days before conducting the division's first airborne operation, a combat drop on the Tagaytay Ridge. Reunited, the division participated in the Liberation of Manila, and two companies of divisional paratroopers conducted an audacious raid on the Los Baños internment camp, liberating two thousand civilians. The 11th Airborne's last combat operation of World War II was in the north of Luzon around Aparri, in aid of combined American and Philippine forces who were battling to subdue the remaining Japanese resistance on the island.
